I'm a proud mommy blogger with a handful of faithful readers (and I do mean handful, but I'm grateful for every one of them).  I've been keeping one since 2003 or so and think of it as journaling in public. http://earthshoes41.blogspot.com/  Most frequently covered topics: my kids, my husband, gardening, dogs, observations about those around me, what I'm reading or listening to. Occasionally I rant about whatever's pissed me off or inspired me that day (social consciousness rants). Once in a while I talk about the ins and outs of writing and whatever I'm working on at the time. Once in a very rare while, I sell a story. Most of the time I don't.
